PCV system question

Hey guys, I just got my PCV sytem working again today but had a few questions on it. When i pull the hose off the intake tube(aftermarket) and valve cover there is air being blown out of valve cover. Is that supposed to happen? If i put my finger over it, it sucks it toward valve cover but if i just put it close its blowing on it.

yeah its supposed to have positive pressure so its best to leave it connected to the intake. I removed all the ugly tubes and bought new tubes and just hooked it the way its supposed to be.

oh ok. thank you man

here is a pic of how I had mine set, nothing really special.

ok nice setup. and if you pull the hose off intake tube it blows air out hose?
